The SPDSCONV
utility changes the format of SPD Server 3.x tables to SPD Server
4.x tables. The conversion is not reversible. Once you convert a
table for use with SPD Server 4.x, the table cannot be read any longer
by SPD Server 3.x. Before you start converting SPD Server tables,
you should fully back up all of your existing SPD Server 3.x tables.
If you ever need to go back to your SPD Server 3.x tables, you can
restore them.
If you
need to temporarily use your tables with SPD Server 3.x and SPD Server
4.x, you can use PROC COPY to make copies of the tables before you
convert them. You can use SPDSCONV on the copied versions to convert
them for use with SPD Server 4.5, while maintaining archival versions
of the SPD Server 3.x tables.
